Research on line loss calculation methods for low voltage distribution networks
In response to the continuous improvement of requirements for distribution network management,accurate calculation of line loss is becoming increasingly important.Therefore,this article introduces three calculation methods:equivalent resistance method,split phase equivalent resistance method,and voltage loss rate method.An actual three-phase unbalanced low-voltage distribution network is selected as a case study.Through analysis,it is found that when calculating the load of three-phase unbalanced low-voltage distribution network,the calculation results using the sub item equivalent resistance method are the most accurate,which can improve the economic benefits of power supply companies and has certain application value.
